ing is a specification.

This invention relates to agricultural implements and particularly to an improved motor driven machine for operatin upon the soil either to prepare the same or the reception of seed or to cultivate the growing plants.

The invention has articular reference to. that class of motor riven machines which are provided with reversing gear, enabling the sup orting truck or vehicle to be driven in two irections, thereby avoiding the turning about of the machine at the end of a row preparatory to starting in the opposite direction.

The present invention has for its object to provide simple and improved mechanism or reversing the earth-engaging im lements at the end of the row, thereby ma ing one set of implements do the work where two sets are usually employed in this class of machines.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully and particularly ptiinted out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the )recise structural details therein exhibited, but at changes, alterations and m cation within the scope of the claims may be resorted to when desired.

Qorresponding parts in the several figures are denoted by i e characters of. reference.

The body or platform 1 of the improved I machine is provided with arch axles 2 and 3 flllllpped with support-ing wheels 4, 5. One 0 the axles, 2, is suitably supported by means of a rocker iron 6 ing movement of the axle in oing over rough ground, and suitable steering at is rovided whereby the forward whee a may adjusted to guide the machine. The whee s 5 upon the" axle 3 are driven by a transmission including a chain 7 from amotor 8 supported upon the platform. these parts may be of conventional or of any suitable construction which may be sub stantially like that illustrated in Letters Patent No. 962,288, granted to me on the 21st day of June, 1910, although no limit tion is made in this respect.

An arch awoke 9 extends transversely beneath the b or platform 1 between the axles 2 and 3. aid yoke is used to hold the cultivating implements at a. uniform distance from each other. In order to allow this distance to be changed, the yoke, as shown in Fig. 2, may be formed of two arts or members avitriagi overla pin arms 9 ad- 'ustably connec toget on ya means of its or similar fastening m'em rs, such as 10'. The yoke 9 may be connected with the axle 3 havin thednven wheels 5 by means of links 1'0 aving bearings which adjusts ably engage the axle spindles, said links havin terminal books 11 which are connecte in a manner to be hereinafter described with the yoke which may be provided with keepers or 12 to engage The axle 3 vi 1 be regarded as the rear axle and will be so described in contndist-inction to the front axle 2, although it is understood that the machine may e driven in two direc ions by the motor, suitpermitting a swingable reversing gear bein provided for the purpose, as conventional y indicated at 13. The implement carrying yoke is connected with the latform adjacent to the front axle 2 by fiexlble draft elements, such as chains 14, it being understood that said chains may be connected directly with the implement carrying yoke or with the implementcarrying heads mounted upon the latter, as will be presently described. l

The implement carrying heads of the device are mounted upon arms 14 extending laterally from the ends of the yoke 9, and said heads, as shown in Figs. 1 to 6, inclusive, may include brackets 15 which are pivotally connected with said yoke by means of pins or bolts 16 which are longitudinally disposed and which extend also through the hooks 11 of the links 10, thereby assembling the parts securely together. Said pins or bolts 16 also constitute pivots about which the arms or brackets 15 may rotate, said arms or brackets being rovided with upwardly extending lugs 1 supporting rock shafts 18 having detents 19 adapted to engage rack segments 20 which are associated with the arch 9 for the purpose of maintainin the bracket members 15 in adjusted po-' sition with relation to said arch. The rock shafts 18 are each provided with a terminal arm 21 constituting a handle whereby it may be manipulated to disengage the detent 19 from the segment rack 20, thereby enabling the bracket member 15 and the parts associated therewith to be tilted to various adjustments, the parts being retained in adjusted position by the engagement of the detent 19 with the rack segment 20. The handle 21 constitutes a gravity latch whereby the detent upon the rock shaft is maintained in adjusted position with reference to the rack segment.

Each of the bracket members 15 is provided with a forwardly extending vertically apertured arm 22 and with laterally extending longitudinally aperturerl arms or members 23. The latter arms serve to support and to guide for longitudinal reciprocatory movement a rack bar 24 meshing with a rack segment 25 which is pivoted upon a pin or bolt 26 that extends through the vertically apertured arm 22, said rack segment being intimately associated with an inverted U- sha ed gang carrying head 27. The latter, as s own in Fig. 7 of the drawings,may be provided with projections28 interlocking with recesses 29 in the'rack segment 25, which latter may for further security be connected with the head 27 by fastening members, such as rivets 30, passing through alined apertures 31' and 32 in the rack segment 25 and the head 27, respectively, as will be best seen by reference to Fi 7 and 8 of the drawings. It will be an erstood, is rig then, that the gang carrying head idly connected with the rack segment 25-,

and that the latter is in engagement with by links 33 with arms 34 extending from a rock shaft 35 which is fulerumed upon the base 1, said rock shaft beingbprovided with" a lever 36, whereb to eifect the desir carrying heads.

Under the modified construction illustrated in Figs. 9 and 11, the implement oarryin heads, here desi nated H, are provided'wit sleeves S slidably engaging the arms 14' of the yoke 9. upon which said'heads may adjustably mounted by means of belts or fastening members S engagin the sleeves S and the arms of the yoke. W en this construction is resorted to, the sleeves S may be provided with keepers K for engagement with the hooks 11 upon the connecting links 10 whereby said implementcarrying members will be connected with the axle 3. The sleeves S may also be provided with eyesE for engagement with the ends of the flexible connecting members 14.

The earthen aging tools which may consist' of blades 3%, as shown in Figs 1, 2, 3, 4 and, 5, or which may consist of disks 38, as shown in Fig. 9, or other cultivating implements, are suitably associated with the gang carrying heads 27 upon which they may be mounted in any suitable, convenient and Well known manner.

Supported for rotation upon the base or platform 1 of the machine isa shaft 39 having a worm gear 40 meshing with a itniay adjustment of the gang worm 41 upon an upright shaft/42 having at its upper end a, handwheel 43 whereby it may be manip lated to rhtate theshaft 39. The latter is ovided with radiating arms 44 connected links 45 with the ends of the arch 9wl1'ich latter, by. manipulation of the hand wheel of the shaft 42 may be raised or lowered in an ap roximately vertical plane, as will be readiy understood.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood. It will be seen that the wheeled frame of the machine *may be propelled in eitherldireetion, that is'tosay, forwardl or rearwardly, and also-that it may be guided, as may be required. By manipulating the hand wheel 43 of the shaft 42, the shaft 39. may be 0scillated, thus causing the arch 9 equipped with the ganwrrying heads to be raised or lowered. en the arch-is. raised, the machine may be transported: from place to place, and while the ureh'iddn nised posie manipulated After proper adjustment of the gang-carrying heads, the hand wheel 43 of the shaft 42 may be manipulated to rock theshaft 39 so as to lower the gangs to present the earthengaging implements for engagement with.

the ground at the desired depth. When the mac ine. is driven in one direction, stress will be exerted through the links 10 upon the implement carrying parts, thereb forcing the earth en agin implements t rough the ground. l on t e. machine is driven in the opposite direction, stress will be exertedby-the flexible elements 14 upon the implement carrying parts, it being, of

course, understood that the elements or chains 14 maybe adjusted so as to make them sufiiciently taut to operate in the desired manner. Means may be provided for locking the lever 36 and the parts actuated v thereby in adjusted position, such means consisting of a stop member of well known form engaging a quadrant supported upon the frame.

As will be seen. from the foregoing description, the construction of the improved machine or implement is simple and of such a nature as to enable the parts to be very easily and conveniently manipulated to obtain the most satisfactory results.
